This invention relates to a machine for manufacturing metal-chain-mailand specially toa mechanism for producing ringchain-mail iigured in anypattern and in any icolours. Y

According to the invention a multiple wire-feeding-device, carrying anumber ot' differently coloured metal-wires,is operated by acontrol-device so that, according to the pattern, now the one and thenanother coloured wire is brought into the range of the link-formingktools, said control-device for the wire-feeder being controlled,according the desired patte-r1 Jy ene, by two or by incre 151' than twoeccentric disks-or by one eccentric drum, the superposed eccentrics ofwhich t'crm either a closed cylinder or a spiral eX- tending over theentire length of the drum the eccentrics or eccentric drum being ro- 201tatedby anchor-feed-mechanisms which, ac-

cording to the pattern, are iniiuenced by an eccentric mounted on themain eccentricshaft" oi thel chain-mailmachine or of the chain-inailsupporting carriage, and are moved and ted stepwise, either for eachring er for each row of rings.

By means of this arrangement any coloured ligured-ring-chain-midiv canbe made on ring-chain-mail manufacturing-machine, i. e. ring-chain-mailwith transverse striL es, with longitudinal stripes, with 0bliquestripes, with Zig-Zag stripes and the like, and ring-chain-mail with anycoloured figured design.

Only those elements of' the chain-mailmanut'acturing machine areillustrated and will be described which co-operate with the newmechanisms, these elements being: they table-plate 1 of themachine, thebracket 2, the carriagev 3 carrying. the chain-mail, theA guides 4ofthis carriage, the tools-5 for forming the ring-shaped links andtheeccentricshaft 6 of the machine with its bearings 6a.

The mechanism for the production of col-' oured ligured ring-chain-,mailconsists of a wire-feeder 7 ,i having on its Jfront-edge a number,forinstance three superposed wirefeeders 8 in which Vwires9 of/dier'entcolours are guided. The wire-feeder 7 is oscillatably mounted ona'right' axle 10 after the manner of a two-armed lever, and itsrearwardly projecting arm 11 is movedfupy and downso thatvv now the onethen the otheror the third' wire 9 is brought into the rangeotthe'tools' 5 for forming .the vring-shaped links.

The rearwardly projecting arm l1 oflthe wire-feeder 7 is controlled by alink 12, adapted to be oscillated inilateral direction around ahinge-element 18 :andfto be oscil- Y can adopt.

vlated kin forward and rearward directions with said hinge-element 13and with the carryin shaft 14 of the same, a diagonal spring 15, xed atthek one end to the machineframe and attached at the other end to saidlink 12, pulling the same to the right and to the rear. The carryingshaft 14 is secured in two bearings 16, 16 so that it cannot shift inlongitudinal direction. Against the ri ht side of the link 12 bears thefree end o a pressure-rod 17, mounted in the ybearings 16 and shiftablein longitudinal direction to makelthe link 12 Vos'cillate in lateraldirection. lA. roller 18 on the rear side of link 12 rests upon thecircumference of an eccentric 19, mounted on the main driving shaft 6 ofthe chain-mail-machine so that said link can be moved in forward andlbackward direction. VOn the upper end,

The link tion during the interval between the formation oftwo ring-linksby the eccentric 19, whereupon, by a movement of the pressurerod 17 inlateral direction, an oscillating movementis communicated to the link sothat one of the channels 20 is brought into register behind the free endof the rearwardly extending lever-arm 11 of the wire-feeder 7 whereuponthe link 12, by a projecting portionof the eccentric 19, is againoscillated in forwarddirection so that the adjusted channel 20 is pushedover the free end of the rearlever-arm .11 ofthe wire-feeder 7 to bringthe same into another position, i. e. to bring a wire of another colourinto the range of the ring-link forming tools 5.

The pressure-rod 17, which communicates to the link its lateraloscillation, is operated by a tappet-lever 21, on the vertical axle 22of which, having a key and groove connection 72, a feeling lever 23 isarranged so that it can be moved in longitudinal direction and which, bymeans of a feeling roller 24 at it/s free end, feels off thecircumference of an eccentric drum 25, the superposed eccentrics 25a ofwhich yprotrude or recede at their circumferences in accordancewith thedesired design ofthe ring-chain-mail. The lateral lalteration of oneclosed section of a chainas'the pattern or design-section is repeated inthe width of the ring-chain-mail, while f the alteration of design inthe height of the chain-mail, i. e. from one row of ring-shaped linkstothe other row, is controlled by the next higher or next lowereccentric 25a of the eccentric-drum 25, the feeler 23 being shifted inlongitudinal direction at the com- 12 is oscillated in backwarddirecpletion of one row of ring-shaped links on the eccentric-drum ofthe height of one eccentric.

The eccentric drum 25, which is rotatably mounted onta vertical axle 26journalled in a bearing 27, is step-wise rotated by ananchor-feed-mechanism. This anchor-feedmechanismconsists of aratchet-wheel 28, rigid with the eccentric-drum 25 and of ananchor-double pawl 29, composed of two pawls 29a and 296, rigidlyconnected the one with the other and mounted on a lever-arm 30a of ananchor-oscillatable-lever 30, the other lever-arm 30?) of which isoscillated, in opposition to the pull of a spring 31, by a pushing pin33, controlled by an eccentric 32 on the main driving shaft 6. Thedouble pawl 29 isl thus moved to and from the ratchet wheel 28, so thatthis ratchet wheel with the eccentric-drum 25 is rotated by one ofthepawls, for instance 29a, which bears resiliently against thecircumference of the n ratchet wheel 28, while the other pawl 29stopsthis movement by engaging with the Gap between teeth of thekratchet wheel 28. F`he direction of rotation of the eccentricdrum 25 isreversed after completion of a horizontal row of rings by interchangingthe part played by the pawls 29a and 29?). Vith this object in view twoconverging tangential surfaces 34 are arranged on the hub of the doublepawl 29 at the right and left on the pivot-'point of the same, againstwhich tangential surfaces a pressure-spring 35 bears, whereby the doublepawl 29 is oscillated to the one side or to the other side so thateither pawl 29a or pawl 295` 'is resiliently pressed against thecircumference of the ratchet wheel 28. The pressure-spring 35 bearingagainst the guiding surfaces 34 is fixed on a flat slide 38 which isguided in longitudinal direction on the long side of the oscillatablelever 30 in oblong holes by means of screws and has a flat extension 37,bent at right angles, and carrying two vertical pins 38. Between' thesevertical pins 38 engages a horizontal pin 39, fixed on the lower end ofa lever 40 which is bent sidewards and is oscillatably mounted, by meansof a. forwardly directed axle 41, at its upper end in a bearing 42, bentat the top-end at right angles, said lever 40 being connected in frontand behind of said bearing with a downwardly directed short lever arm43, 44 respectively. To the front lever-army 43 the upper end of a lever45, which is bent to the right and oscillatably mounted at its lowerend, is connected said lever-arm 43 having, underneath the connection-point, a. forwardly bent abutment 46. On the carriage 3 carryingthe chain-mail two abutments 47 and 48 are arranged the one 47 of saidabutments being directly fixed on the carriage 3, the other one 48 beingmounted on an extension 49 of the carriage. These abutments serve tomake sition so that said lever48 turns'to the right the llever 40, bentto the left, and through the intermediary of the front short lever 44,Whilethe abutment 48, mounted onthe extension 49 bears, in the lefteXtreme position of carriage 3, against the short lever arm 43behind thebearing 42, whereby the 4lever 40, bent to the left, is oscillate'd totheleft. By the engaging pins 37, 381of lever 40 and slide 36 this slideis pushedfto f, and fro accordingly, so that the pressurespring 35mounted on the slide 36 moves from one surface 34 ofvthedouble pawl 29to :the other pressure-surface and oscillatcs thisfpawl from the onesidetothe other.

Formoving the vfeeler 23 in longitudinal direction on the'eccentric-drum25, thisfeeler-engages, by a transverse-slot 50, over a horizontal stud51 of a rack 52 Whichis vertically gnided in the bearing-body 27 andmeshes Witha spur-Wheel 53 which is rotated from theanchor-feed-mechanism and reversed -When the feeler has felt ofi thehigher or lower eccentric-on the eccentricdrum. Thisanchor-feed-mechanism consists of a ratchet Wheel 54, rigid With a spur-Wheel-53, and rotatable on the same axle and driven by a double pawl 55,mounted on an `oscillatable lever 56, pushed to the right by a spring 57and oscillated to the left-by a'lever 58, acting'upon its free endand-directed-to' the rear in horizontal direction. The pivot-axle ofthis lever 58 is mounted on a horizontal surface of the bearing 42andits front short arm 58a projects forward I into the range o-f anabutment 59, fixed on the carriage 3 and by means of Whichithe lever 58is oscillated, when the carriage-isdn the extreme right position. Anabutment 60 on the extension 49 of the carriage oscil- ^-v lates thelever 58 When-'the carriage 3 is in the left extreme position. In thismanner the feeler is. shifted each time the Width of an eccentric of theeccentric-drum after completion of a horizontal row of rings.

T'Vhen the feeler 23 has arrived in its eX- tremepositions on theeccentric drum 25, one of `the pins 61 on the rack 52 bears against theupper or lovver side-edge of a lever-62 enlarged at this point and whichhas a stationary vpivot-point at the. left` of the rack 52 and in frontof the same on the bearing body, the free, slit end of this leverengaging with a lslide 63, guided on the right long side of theoscillatable lever 56 by means of oblong slots and screws and havingapressure-spring 64, pressing upon tangential-surfaces 55a on the hub ofthe double ',paivl 55 so that this pa'ivl is oscillated, the partsplayed b the two paWls of the double paWl 35 as s ifting and lockingparvis' being reversed, so

that the lon-gitudinalmovementxof? the ifeeler 23 on kthe*'eccentric-drum 25 lis rre'versed..

For-the production ofvlong-striped chainmail serves the mechanism shownin Fig. 7, and which consists of an eccentric-disk 73, mounted at thesame height asthe pressurerod 17 and rotatable arounda vertical-axle,

the pressure-rod 17 `and by the same, through the intermediary of thelink l2, thewire feeding-device v7 being control-led, according to the4desired design; by the projectingandreceiving portions ofthecircumference ofsaid eccentric-disk. The eccentric-disk 73vi's rotatedby a ratchet wheel y28 connected with the same and by the elements 29 to49 which have been above described.

For theV production of` transversefstriped chain-mail, a mechanism isdesigned as shown in Fig.i 8. It consists of a cam-disk 74 which bythetappets 59 and 60 of said carriage and by the lever 58 which has on itsfree vend a spring-controlled pawl 75 and is itself pulled back by theaction of a spring k7 6. Fig. 9 shows a mechanism for the production ofobliquely-striped chain-mail comprising, besides the mechanism forproducing long-stripedchainmail shown in Fig. 7, .a special device for.altering kthe lateral successio'n of the colouring of the chain-mailfrom one ring-row to the other ring-row of one-or several ring-widths.This ydisplacing.

device consists of a locking beam 77 mounted, over the ratchet wheel 28arranged at some distance above. the cam disk 73, on a bolt 78 extendinghorizontally from the bearing bolt of the cam-disk 7 Band on theratchet-wheel 28 so that. it rcan move up and down like aA scale-beam,andon a stud 78a of bolt 78so that it can oscillate in forward andbackward directions, its arms 77 a,'moving in' forward and downwarddirections, projecting with its end face', bevelled accordingly, to theouter circumference of the ratchet-wheel 28 and prevents thusthecorresponding pawl 29a of the double-pawl 29 from coming into engagementwith the ratchet wheel 28. T he locking beam 77 is held in the lockingposition by a pressure-spring 79, oscillatable on a column 80 by meansof a handle 81 and' bearing, according to its adjusting,-against thesurface of the one or other arm 7 7a, 7 7 of the locking beam to pressdownward the corresponding arm, for instance 77 a, and to hold the samein its forwardly oscillated position. Under the locking beam 77 and itsbearing7 8 a plate 82 is oscillatable on the ratchet-wheel 28 and aroundthe axleof the'same, said plate having at its extreme lateral' endsteeth 83, which are arranged underneath the locking position of thelocking surfaces of the locking beam 77 and project over the outercircumference of the ratchet-,wheel 28 and over the locking surface ofthe locking beam 77, said plate having two-verticalpins 84 @rippingbehind the locking beam 77. This mechanism serves to bring the lockingbeam' 77 after its action,

` the interru )tion of the colour 'chan ino' of l g s an intervalbetween rings, out of its locking position. The pawl 29a which rotatesthe ratchet wheel 28, when it is in vworking po-y sition, is preventedby the locking-beam 77 from engaging with the ratchet-wheel 28 ,it comeshowever, in the course of its forward movement, into engagement with theproj ecting tooth 83 of plate 82 and rotates the same whereby the-plate82, by means of one of its vertical-pins SLgripping behind the notengaged arm7 7 b of the locking beam 77 pushes j the locking-arm 77 a ofthe locking-beam 77 to the rear so ythat the locking surface of the samemovesaway from the circumference of the ratchet-wheel 28 and releasesthus the step-wise movement of theratchet-wheel 28 and of the cam-disk73 for the row of rings which has been just begun. At the end of thisrow of rings `the double-pawl 29 is reversed by means of the elements 34to 48 above described so that the other pawl 2912 comes nowintokengagement with the ratchet-wheel 28 but at the same time with thesecond tooth 83 of plate 82 projecting on this side sothat, at theirstpart-rotation of the ratchet-wheel 28, it rotates also this plate.The other ver tical-pin 84'of plate 82 is thus made to 'bear against thearm 77a ofthe locking-bolt 77, which has, va little while ago beenoscillated out of the locking-position and pushes the same again intothe locking position.. When the elements are in the'position shown inFig. y9 thef striped pattern is shifted to the right one ring-shaped,link so that a chainma'il is produced which is striped from the rightabove toleft below. lrVhen the spring 79 is oscllated beyond thepivot-point of the y82 and when the pins 84 are placed farther backaccordingly, the locking beam 77 will vbe brought out of the lockingposition only after an accordingly Agreater forward movenient of thedouble-pawl 29, the colour changing being displaced several ring-linksso that the angle of inclination of the striped-pattern is alteredaccordingly. f

The mechanism shown in Fig. 10 is designed for the production ofring-chain-mail patterned in zig-zag. It consists of a camdisk 85 which,by means of a ratchet-wheel 87, rigidlyconnected with it'by screws 86,and by the elements 58` to 60 and 75, 76 described above, is rotated onestep at each changing of the row of rings.

f The circumference ofthis cam-disk projects, in accordance with theheight of the change of direction` of the zig-zag pattern, and brings,by means of a feelerv 88 moving over its circumference and fixed on thehandle 81 'of spring 79, this pressure-spring 79 pulled to the right bythe action of a pullspring 79 over the locking beam 77 of thecolour-control-mechauism, constructed shown in Fig. 9 and situated on alower plane, into a. position alternately at the right and left of thepivot-point of the locking lbeam 7 7, whereby this locking beam 77 isnow displaced to the right and then to the left, ef-

fecting thereby the shifting of the 'zig-Zag pattern. y

In this case the oscillating movement of the link 12 is not eected bythe pressurerod 17, thisbeing locked in its position. The locking of thesupporting-axle .11i of link 12 is released, and the driving mechanismas fshown in Fig. 9 acts upon this axle 1l and shifts the same inlateral direction. The link 12 oscillates consequently around thestationary supporting point etfthe left end of the pressure-rod 17 whichis now locked (see -Fig. 11). Y

Another kind of chain-mail-pattern can be produced by changing thecolour-succession-at the same time as the direction of the Zig-zagpattern is changed. A design is thus produced, constitutingof-horizontal rows of rhomboids mutuallyy alternating as regards 'colourand inclined alternately to the right and to the left. In order toproduce this lcolour-alternation,'together with the alternation ofdirection in the zigzag-design, a second cam-disk .89 is fixed betweenthe cain-disk and the ratchet-wheel S7 of the same, in theV mechanismshown in Figs. 9, 10 and 11, said' secondV cam-disk 89 serving again to`move the pressure-rod 17 to and fro in accordance with thedisplacing-mechanism. When the pressure-rod is in the pulledbackposition, the vlink 12 would be moved only by the releasedsupporting axle 14 moved in longitudinal direction under the action ofcam-disk 73, and the-control-lever 11 of the wire-feeder 7 will forinstance be influenced only by the central and left deflection-channelsof'the saine. When the central wire in the wire-feeder is red and whenthe upper deflecting-channel, corresponding to the redr wire in thewire-feeder so that the design, beginning:new with red, alters from'redYto whiteV owing-to the similar movement of the -supporting .axle Vwhichmakes the ring row oscillatebetween its central and rightdeflecting-channels.

In the mechanism shown in Figs. 1 to 6 for the production of figuredpattern-chainmail an eccentric drum with spiral-eccentrics 91 mergingthe onefinto the other as shown in Fig. 14 may be used instead of aneccentric-drum 25 with closed eccentiics 25a,

guiding edges 92 being arranged 'between the spiral-windings helicallyextending over the entire length of the drum, said guiding edgesprojecting over these windings, the lfeeder 23 being guided, by means ofits pulley 24 between these guiding edges so that it is moved along theeccentric-drum withoutthe special lifting and lowering mechanism 50 to58, the disengaging rmechanism (35 to 71 being also not necessary. Thearrangement just described is however adapted, owing to the greaterlength of the eccentric-drum, only for less high pattern-sections.
